Answer:
3(n-5)=2n+16
Step-by-step explanation:
3 lots of 'n' <em>and </em>5 means 3 times both values so these values are put into a bracket with a common multiplier (ie. the 3)
3(5 - n)
16 more than 2 lots of 'n' means that n has to be doubled. n + n = 2n. add 16 to this and we have
2n + 16
if these values are both equal (hence why they are in an equation) then all that is needed is for them to be set equal alongside each other.
3(n-5) = 2n+16

Step-by-step explanation:
a) 4(x + 2)=4x+8
b) 2(3x - 4) =6x-8
c) 4(3 - 6x) 2x + 18-2(2 – 3x)
B(b^2+49)
